For most recovery and recycling equipment, these requirements are detailed in Appendix B2 to 40 CFR 82, Subpart F. Requirements for equipment manufactured or imported after January 1, 2017, are detailed in Appendix B3 (for non-flammable refrigerants) or Appendix B4 (for flammable refrigerants). These standards are based on the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 740 test protocol. Small appliance recovery and recycling equipment may be tested under these requirements or the ones detailed in Appendix C to 40 CFR 82, Subpart F.

Recovery equipment standards vary depending on the size and type of air-conditioning or refrigeration appliance being serviced:

Certified equipment can be identified by a label that states: "This equipment has been certified by AHRI/UL to meet EPA's minimum requirements for recycling and/or recovery equipment intended for use with [appropriate category of appliance]."

Certification by Owners of Refrigerant Recovery and Recycling Equipment

EPA no longer requires that persons servicing air-conditioning and refrigeration equipment certify that they have acquired refrigerant recovery or recycling equipment and that they are complying with the applicable requirements.
